Does iCloud sync for users not currently logged into a device?
Does iCloud sync for users with an account on a device but are not logged in?
I have a Mac mini running as a server. I have set this up to fully sync iCloud for 3 Apple family member accounts (i.e. it is not optimising storage and downloads all files and photos etc.). This acts as a full backup. Additionally, it backs-up via Timemachine to an external drive so deleted files can be recovered.
I've been unable to verify if iCloud (i.e. files, photos etc) sync from the cloud for users not logged into the Mac mini. All my devices use the latest (non-beta) software.
Mac mini, macOS 11.5
